Gerard Bouchar updated NUTCH-2589:
----------------------------------
Description:
Html redirections using meta tags are supported in nutch. They work well when
using parse-html to parse files. However, when using parse-tika, they are not
detected.
This is because of https://issues.apache.org/jira/browse/TIKA-2652
Tika emits redirection meta tags as :
{code:xml}
<meta name="refresh" content="0; url=http://example.com"/>
{code}
whereas org.apache.nutch.parse.tika.HTMLMetaProcessor expects meta tags having
the following format :
{code:xml}
<meta http-equiv="refresh" content="0; url=http://example.com";>
{code}
The bug can be reproduced with the following nutch-site.xml:
{code:xml}
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<!-- Put site-specific property overrides in this file. -->
<configuration>
<property>
<name>plugin.includes</name>
<value>protocol-http|parse-tika</value>
</property>
<property>
<name>http.agent.name</name>
<value>blah</value>
</property>
</configuration>
{code}
fetching this url: http://www.google.com/policies/technologies/ads/
The resulting status is {code}success(1,0){code} whereas using parse-html, the
resulting status is {code:html}success(1,100),
args[0]=https://policies.google.com/technologies/ads, args[1]=0{code}
